Fixedly grinding ring 116 to small part is made by the electrical conductance material, such as metal.Rotation shredder plate assemblies 112 is also made by the electrical conductance material to small part, such as metal.Rotation shredder plate assemblies 112 comprises lug 120, and this lug 120 presses against fixedly on the grinding ring 116 food refuse with the rubbish crumble into fractions.In the embodiment shown in fig. 1, lug 120 is connected on the dish 122 by rivet 124, makes that lug 120 can be with respect to dish 122 rotations (Fig. 1 only illustrates a lug 120).In other embodiments, lug 120 is securely connected on dish 122, thereby can not rotate.When food refuse was ground into enough little particulate matter, this particulate matter, was discharged by outlet 128 together with the water that injects processor from rotating process on the shredder plate assemblies 112.
On the one hand, adapter ring 115 is by electrical conductance resin-based materials casting, such as can be from the Integral Technologies of washingtonian Bellingham, the ElectriPlast that Inc. buys.
Fig. 2 shows the structure chart of the others of processor 100.Detector 200 is connected to grinding mechanism 110 with the existing of the foreign matter conductive body of 100 li of detection processors, such as silverware or other ironware.Among some embodiment, detector 200 be connected to motor 106 with echo probe to 100 li of processors the foreign matter conductive body and control motor 106.For example,, then can close processor immediately, and/or start brake to stop axle 118 and rotation shredder plate assemblies 112 if detector 200 detects the foreign matter conductive body of 110 li of grinding mechanisms.
In the exemplary embodiment, detector 200 makes rotation shredder plate assemblies 112 when fixedly the circuit between the grinding ring 112 is complete detecting by the foreign matter conductive body, the existence of the foreign matter conductive body that the detection grinding mechanism is 110 li.On the one hand, detector detects fixedly between grinding ring and the rotation shredder plate assemblies has electric continuity such as short circuit, then determines being present in the grinding mechanism of foreign matter conductive body.Detector 200 has the terminal 204 that is connected to fixing grinding ring 116 (directly or via the electricity of the processor 100 that contact with fixing grinding ring 116 leading parts) and another terminal 206 that is connected to rotation shredder plate assemblies 112, passes through the motor reel bearing usually.On the one hand, a terminal 204,206 is connected to ground, and voltage is applied to another terminal 204,206.Usually, the parts of shredder plate assemblies 112 comprise lug 120 and dish 122, do not contact fixedly grinding ring 116.If the foreign matter conductive body such as silverware, falls into 110 li of grinding mechanisms, it may contact rotation shredder plate assemblies 112 and fixing grinding ring 116, and closure is connected to the circuit between herein the terminal 204,206.
Fig. 3 shows the circuit diagram of exemplary detector 200.The effect of detector 200 is existence of foreign matter conductive body of 110 li of the grinding mechanisms of detection processor 100.Detector 200 comprises detection circuit 202, and it has and is connected to the fixedly terminal 204 of grinding ring 116, and the terminal 206 that is connected to rotation shredder plate assemblies 112 by the bearing of motor reel 118.In the embodiment shown, detection circuit 202 applies low pressure and arrives fixedly grinding ring terminal 204, and rotation grating disk terminal 206 ground connection.On the one hand, low pressure is about 0.25 volt of alternating current.The magnitude of current that flows through between detection circuit 202 response terminals 204 and 206.Water and food refuse are only arranged in the processor, bigger resistance is arranged between the terminal 204 and 206, and only have little electric current to flow through.If the foreign matter conductive body has contacted rotation shredder plate assemblies 112 and fixing grinding ring 116,,, and will between terminal 204 and 206, flow through higher electric current such as short circuit then in rotation shredder plate assemblies 112 with fixedly between the grinding ring 116 low resistance is arranged.Respond this higher electric current, detector 200 detects grinding mechanism has the foreign matter conductive body for 110 li.
If the foreign matter conductive body fell into 110 li of grinding mechanisms before processor 100 starts, then object may only contact fixedly grinding ring 116 or shredder plate assemblies 112, is not to contact both simultaneously.Therefore in this case, the foreign matter conductive body does not have the circuit between closed terminal 204 and 206, processor start and motor 106 start before the existence that detects less than the foreign matter conductive body of detector 200.According to explanation of the present disclosure, by power supply in short-term, controller 210 is with " collision " motor 106.Motor reel 118 rotates, thereby rotation shredder plate assemblies 112 is rotated on a small quantity.Usually, the small movements of rotation shredder plate assemblies 112 makes it contact fixedly grinding ring 116 and parts that rotate shredder plate assemblies 112 simultaneously mobile foreign matter conductive body, thereby detects its existence.If do not detect the foreign matter conductive body, then motor 106 energising full speed runnings.In case the processor running has the foreign matter conductive body for 110 li if detect grinding mechanism, then will remove power supply by relay 212.
In a kind of variation, when for the first time to food refuse disposer 100 power supplies, in the existence of before motor 106 power supplies, checking 110 li foreign matter conductive bodies of grinding mechanism with detector 200.The existence of having only detector 200 to survey less than 110 li foreign matter conductive bodies of grinding mechanism is just to motor 106 power supplies.Motor 106 can be powered or as above-mentioned temporary transient power supply fully.
Fig. 4 shows another optional detector 200a, and it is unlike the controller 210 that comprises embodiment illustrated in fig. 3.Detector 200a is connected to independently on the motor controller 250, with indication motor controller 250 when detecting the existing of foreign matter conductive body.Detector 200 as shown in Figure 3, terminal 204 and 206 is connected on the grinding mechanism 110, and detects the existence of foreign matter conductive body by the higher electric current that response is flowed between terminal 204 and 206.Should be appreciated that in simple embodiment, motor controller 250 can be an on-off circuit, as relay, response detector 200a close when detecting existing of foreign matter conductive body (for example, open relay the contact and with the relay outage).
In other optional embodiment, detection circuit uses the earth-fault finder chip.In response to the existence of 110 li foreign matter conductive bodies of grinding mechanism, earth-fault finder tripping operation (trip) is to break to the power supply of processor motor 106.
Fig. 5 shows exemplary embodiment, wherein uses earth fault contact maker 500 in response to the existence of 110 li foreign matter conductive bodies of grinding mechanism processor 100 to be cut off the power supply.Earth fault contact maker 500 is connected and exchanges between main line 502 and the processor 100.LVPS 504 is to detector circuit 506 power supplies, and this detector circuit 506 comprises constant-voltage power supply testing circuit 508, benchmark 510 and comparator 512.Constant-voltage power supply testing circuit 508 applies constant voltage to rotation shredder plate assemblies 112 and fixing grinding ring 116, and output voltage is to the input of comparator 512, the indication rotation shredder plate assemblies 112 and the fixing magnitude of current between the grinding ring 116.The existence closure of 110 li foreign matter conductive bodies of grinding mechanism rotation shredder plate assemblies 112 and the fixing circuit between the grinding ring 116, make rotation shredder plate assemblies 112 and the fixedly increase of the electric current between the grinding ring 116.This causes that constant-voltage power supply testing circuit 508 outputs to the variation of the voltage of comparator 512 inputs.In response to this voltage change, comparator 512 is to two-way triode output optical coupler (triac output optocoupler) 514 power supply, and this two-way triode output optical coupler 514 will be connected with ground wire from interchange main line 502 from the alive circuit that exchanges main line 502 by resistor 516.This causes the imbalance through the electric current of alive circuit that exchanges main line 502 certainly and center line.Earth fault contact maker 500 responds these current imbalances and trips, and cuts off the power supply of processor 100.
Can periodically power to detection circuit 202, rather than continuous running, because the low-level electric current that continues can cause electrolysis for 110 li at grinding mechanism.In certain embodiments, provide and surmounted control (override) to avoid detector when needed.For example, some food refuses more have conductibility than other article.The conductibility food refuses (such as the sauce that mixes with rice) that 110 li of grinding mechanisms wash out with water not too easily may cause that detector 200 cancels the power supply to motor 106 in unnecessary.Surmounting control allows grinding mechanism 110 to remain in operation to wash away from processor up to the conductibility food refuse.This surmounts control can exemplarily be switch, and such as switch 214 shown in dotted lines in Figure 2, the user can close it with the super control detector 200 that relaxes.
On the one hand, detector 200 when detecting 110 li of grinding mechanisms and have the foreign matter conductive body to exist, to the indicator power supply, the lamp 216 shown in Fig. 2 dotted line, its caution user has detected the foreign matter conductive body for 110 li at grinding mechanism.Should be appreciated that indicator can be that any kind can be to the device of user's warning, such as audible alarm.
